CHAIR-LEG EXTENSION.

Specification of Letters Patent;

Application filed April 9, 1918. Serial 'No. 227,588.

To all whom it may concern:

Be it known that .1, JOHN Di'r'rnrolg, a

subject of the King of Great Britain, and

resident of the town of Perth, in the Province of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Chair-Leg Extensions, of which the following is a specification.

This invention relates to improvements in chair leg extensions, and the objects of the invention are to devise a simple and effective device by which the legs of a chair may be extended to convert it into a high chair, suitable for children, and it consists essentially of the improved construction, hereinafter described-"in detail in the accompanying specification and drawing.

In the drawings: Figure 1 is a. perspective view of the taxtension device on a chair.

Fig. 2 is a vertical section of one leg. Fig. 3 is a cross section. Fig.4 shows a modification of the extension members. V

In the drawings, like characters of reference refer to corresponding parts in the Referring to the drawings, A represents a chair of any usual construction, and 'B represents my'extension members each comprising an extension piece 10 of. ,wood or other convenient material, and an engagin member 11 adapted to fit around the leg 0,

the chair, this member being conveniently formed of metal in U-shape and-cross section, and rigidly attached to the extension piece 10 by screws, nails or the like.

The engaging member 11 is formed with projecting sldes 12, and diagonally opposite the engaging member are connected together and held in position on the chair leg by suit able tie rods 13, the chair being engaged with bails or shackles 14 connected to the extensions 12.

The tie rods 13 maybe of any suitable material, of cord or string if desired. Suit' able means are provided for tightening them, the means I have shown comprising turn buckles l5.

It will bev seen that the pressure exerted on the chair'leg at the tie rodsl3 will cause the extension members B to be held firmly in position and to construct a rigid support for the chair leg. 1 In the form shown in Fig. 4, thumbscrews 20 extend into the engaging members 21. These thumbscrews are connected to the tie rods and thereby permit adjustment of the length of the same.

The engaging members in either form of the invention, if made of sheet metal, will be flexible and may be conformed to the shape of any leg whether square, fiat, or

round. I g

'As many changes could. be made in the above construction anti many apparently widely different embodiments of my invention, within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specifij.cation and drawings shall be interpreted as illustrative and 'not'in a limiting sense. What I claim as my invention is:

A chair leg extension device consistin of extension pieces having upper horizontasurfaces, engaging members secured to the extensions and forming sockets to receive the chair le S and tie rods between the en- 1 gaging mem ers, the parts being constructed and'arrangedso as article capable of immediate use.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
